ADVERTISING APPARATUS.

Patented J an. 1, 1907.

Application led July 27,1905. Serial No. 271,538'.

v lng 1s a specification.

The invention has for its object an advertising device of the kind inwhich an advertisement-band is drawn intermittently-off one drum and wound upon another, whereupon as soon as the band has been wound from one drum to the other inv this manner it is rewound upon the first drum in the `opposite direction.

The invention relates to a particular con-1 struction of such an advertising device, and more particularly to the apparatus for imparting the intermittent movement to the advertising-band, the device being differentiated from known-apparatuses of the kind owing to its simplicity and reliability.

A constructional form'of the novel advertising device is illustrated inthe accompanying drawings. 4

Figure l is anend elevation of the advertising device or of the mechanism for operating the drums. Figs. 2 and 3 aresimilar views to Fig. 1, but showing the various parts in different o erative positions and certain parts removed fr the purpose of clearly showing the construction and operation:` Fig. 4 is a front elevation corresponding to Fig. 3. Figs. 5 to 16, inclusive, `'show details of the apparatus on anenlarged scale. i

The two drums a and t, upon which the advertisement-band c, Fig. 4, is wound alternately with intermittent movement, are mounted in an appro riate frame and are connected by a suitab e chain-gear :d e f, so that when the chain f is dis laced in either direction the drums a and receive a corresponding rotary displacement.

U onthe side wall of the apparatus a sliding ame g, Figs. 5 and 6, of thenature of a cross-head ismounted in suitable guides and is adapted to be raised or lowered by a shaft h, driven -in'any convenient manner by the intermediary of a crank c, balanced by a counterweight i and a connecting-rod l. When the crank c is rotated toward the right hand, the connecting -rodl raises the sliding approximately from the position shown in frame Fig. l to that representedin Fig. 2. i Thereupon a spring-controlled pawl m, Figs. 7 and.

8, arranged upon the sliding-frame, snaps over one of the pins n, with which the chainf is provided at suitable intervals, Fig. 4. lf the rotation of the crank 7c is continued, in the first place the frame g ascendssomewhat farther and upon reaching its uppermost position it descends, Fig. 3 whereupon .the pawl m, acting upon the pin n, draws the chain f down with it, so that the drums a and t receive a right-hand rotation, by means of` which the advertising-band is wound from the upper onto the lower drum.` This windy ing movement continues as long as the chain is drawn downward-,that is to say, until the sliding frame has reached its lowermost position, Fig. 1, and again begins toy ascenda The pawl m then leaves the fpin n, which remains stationary, and-'shortly before thesliding frame againreaches its uppermost posil tion it snaps over the next pin n, and during the succeeding downward travel of thesliding framethe chain is again drawn downward. During` the lascent of the sliding frame the chain thereforev remains at rest, while, on the other hand, each downward movement of the sliding frame displaces the chain-that is to say, draws it downward by the amount of the interval separating ltwo adjacent pins n. ln-this latter case the advertisement-band is also dis laced, whilein the former case the band is left in the'posi- 4tion into which its intermittent movement has carried it and there remains in view for a certain period.

When the winding of theadvertisementband from the drum a, onto the drum t is completed, or nearly so, the band is. again wound with an intermittent movement onto the drum a, and lthis without interrupting the operation of the advertising device or altering the direction of rotation of the crank lc. This result'is attained owing to the ,fact that at the proper moment the pawl m is released-that is to say, it is withdrawn from the path of the pins ra*while at the same time asimilar pawl o upon the other side of the sliding frame g is interposed in the path of ythe pins n on the left-hand length of the IOO The enga ement and disengagement of the pawls m an o are effected by means of a camdsk p, Figs. 9 and 10, provided with a cntaway section p', which is rotated by a predetermined amount by means oi a ratchetwheel g, Figs. 9 and 10, connected with it, and of an operating-lever r, Figs. 11 and 12, with pawl s upon each ascent of the sliding frame. The rocking movement required to actuate the lever r is effected by means of the guide slot t, running in an appropriatelyv inclined direction in the wall oi' the apparatus, the operating-lever engaging in this slot t by means of a pin 1"', Figs. 11 and 12. Now'according as the full edge or the recessed edge of the cam-disk acts against the pin m or the pin o of the pawls m or o, respectively, the pawl m or the pawl o is held in such a manner path of the pins fn, or outside the same. In the example here illustrated7 in which the pawls m and 0 are connected by a lcommon spring u, Figs. 7 and 8, the position oi the cani-disk gaged whi e the pawl 0 is disengaged as the pawl-pins m and o slide over the recessed and the full ortions of the cam-disk, respectively. ow as soon as, owing to the `further rotation of the cam-disk, the pin m comes upon the full edge of the disk and the pin o u on the recessed portion, which is the case W en the advertisement-band is unwound from the drum a, the position of the pawls is reversed-that is to say, the pawl 'm is disengaged and the pawl o is engaged.

Now and again it may be desirable to disengage both the pawls m and o. This is eifected by means of a lever i), Figs. 1, 12, and 13, which when rocked into the horizontal position acts by its chamfered ends fv, Figs. 12 and 13, against appropriate pins m2 and o2 oi' the pawls, Figs. 7 and 8, and holds both these latter in the disengaged position. If

it should be omitted to move back the lever i) when the a paratus is restarted, the reversal of this ever will be effected automatas upon the ascent of the sliding frame an arm v2 on ythe lever will strike against a pin w, thereby rocking the lever c back into the position shown in Fig. 1, thus rengaging either the pawl m or the pawl 0. The apparatus is thereby prevented from running idly-that is to say, without displacing thev advertisement-band.

In order to prevent overrunning of the drum a and to hold it while the advertisement-band is stationary, the following provision is made: Upon the wall of the drum a is arranged a pin a', which is normally held between two spring-locking pawls x and Figs. 15 and 16. ln the upward movement a pin g', Figs. 1, 2, 3, 5, and 6, ofthe sliding frame strikes against a bent lever y, Figs. 1, 2, 3, 15, and 16, by the displacement of which into the position represented in'Fig. 2 the that it lies either in the' p is such that the pawl m is enout of reach of the locking-pawls x-a projection g2, Figs. 1, 2, 3, 5, and 6, upon the descending sliding frame by acting upon a pin w, Figs. 1, 2, 3, 15, and 16, on the supporting-lever presses this latter aside, whereby the bent lever y is again released, so that both it and the locking-pawls and return to their initial position, Fig. 3. Upon the completion of the downward movement of the sliding frame and of the rotation lof the drum a the in a again'comes between the locking-paw s, pressing the pawl m" to one side in order to do so, and is again held between these pawls, Fig. 1'.y

Having now fully described my invention, what I claim as new is- 1. An advertising apparatus comprising a frame, se arated and oppositely-disposed rotatable ruins supported in said frame, an advertiseinent-band adapted to be wound from one drum to the other, an endless chain geared to the oppositely-disposed drums and capable of rotating the same and moving the advertisement-band, a sliding frame adapted to reciprocate between the drums and adjacent to the endless chain, a pawl on each side of the sliding frame either one of which is adapted to engage the endless chain and oppositely move the same, means for reci rocatingthe sliding frame whereby the en less chain and advertisement-band is intermittently displaced.
